## Emily778 2 years ago Which theorem or postulate proves the two triangles are similar?

1. Emily778

S-S-A

3. Emily778

you mean SAS?

yeah, that's same

5. ganeshie8

this is same as previous question, i would tick AA similarity

6. Emily778

tHANKS

7. jim_thompson5910

it's neither SSA or AA

8. jim_thompson5910

and it's not SAS

9. jim_thompson5910
10. ganeshie8

how ?

11. jim_thompson5910

actually..hmm I guess you could use AA, nvm but SSS works too

12. Emily778

What is it?? :(

13. ganeshie8

you mean SAS works too ?

14. jim_thompson5910

no SSS

15. jim_thompson5910

that page I posted explains

16. jim_thompson5910

from that page "SSS Similarity Theorem This theorem states that if the sides of two triangles are in proportion, then the triangles are similar."

17. Emily778

so, it's SSS?

18. ganeshie8

no jim, all 3 pairs of sides need to form a proportion for SSS to work

19. jim_thompson5910

SSS would have been my first choice....but AA works as well (you need to do a bit of work, not much though)

20. jim_thompson5910

actually you just need 2 pairs and SSS works

21. Emily778

This is worth a lot of points... :(

22. ganeshie8

all 3 pairs of sides need to have same ratio, jim. only 2 side ratios matching wont do for SSS

23. jim_thompson5910

hmm this page is odd, they use SSS first, then SAS nvm, i guess it's not accurate go for AA

good point ganeshie8

26. ganeshie8
